[BackupPC-users] Using NFS to increase backup speed

2014-10-16 Thread Sorin Srbu
Hi all, I'm seeing network speeds at about 35-45 Mbps when using BackupPC and rsync over ssh. Running iperf below I notice the network should theoretically be capable of a bit more than that. I understand that ssh adds quite a bit of bottleneck. [root@titan ~]# iperf -c cyndane ---

What about testing the speed over the ssh tunnel? That may tell you whether ssh is slowing down your transfers or that it's due to rsync. If it is ssh, you could trade encryption strength for speed. Best, Koen On October 16, 2014 2:25:53 PM CEST, Sorin Srbu wrote: >Hi all, > >I'm seeing

You may wish to prevent ssh from using compression when using a fast link, the overhead probably isn't worth it and may give you a reasonable boost in throughput. Like Koen said, you'll want to benchmark the different scenarios. Regards, Colin On 16/10/14 16:28, Koen Vermeer wrote: What abo
